Earning New Proffesions and Races Also a New PvP and PvE concept

First of all sorry for one thread, but I was too lazy to make 2.
Idea #1:
I think that maybe you should be able to earn new professions and/or races to play as whiel you progress through the game. After completing missions and quests the rewards could be proffessions and races. This would be really cool, especially if you could earn some really good stuff to play as. Like maybe even play as a spirit type thing, similar to the thing you are when you die and are going to look for your body in WoW.
For example, you complete the Sanctum Cay mission. This is sort of the end of the White Mantle. You can now play as the White Mantle, but you aren't evil. They don't recognize you as a Whte Mantle or anything, you just look different, and have different armor, maybe diff. weapons and skills. Or you could be a dwarf after completing all the Shiverpeak missions.
Idea #2:
This is my new idea for PVE/PVP. You are able to play as enemies, maybe unlocking them through the system mentioned above. You have a different set of missions and a different storyline than the main characters. The enemy storyline would be a lot shorter, and maybe they would just have quests and not main missions. The main idea of the enemy concept is that you can do some of the missions against regular characters. You would be able to be charr in nolani academy for example. You would be able to kill the good guys. It's basically similar to the Horde and Alliance in WoW. It would be cool if maybe there were some areas where you would leave from a city and end up in an area on a quest, and the enemys quest is to kill you. If there weren't enough human enemies, there would be regular NPC's. There would have to be a max # of human players that could be in a zone at a time. With the quests, sometime the good guys would have the quest and the bad guys would stop them,a nd sometimes the bad guys would have the quest and the good guys would stop them. In this area there would still be NPC enemies, but some of them would be substituted for human players. I don't know if it would be better to have people make their parties, or have random grouping. Also, I don't think PVP characters should be allowed to go in these areas, since it is basically PVE, with a f ew PVP elements mixed in.
To kind of put my 2 ideas together, maybe you would have to complete a mission or quest with your normal character before doing it with an enemy. Maybe even enemies could be allowed in normalk PVP arenas... just a thought
Please give input on both of these topics and hopefully Anet will see these and put them in the game. Sorry for the WoW references, but I just played it the other day so I got some ideas.

EDIT: Well we got the factions, maybe some of these other ideas could fit in.

I know it's kind of long, but if you read my post, then can you at least post a reply saying what you think of it, any suggestions, etc. These ideas could be implemented into the game, but they may need some suggestions. If people express interest in this, Anet is more likely to put it in the game.

eh, it'd be hard to do that in GW do to the lack of classes. Good concept though, for a game like WoW

Well I think that if they added some more classes (do you mean professions?)this could work. They might have to maybe have you unlock skills that you can only get this way instead of unlocking races and professions. Idea #2 can be implemented with the current amount of professions I think. They would need at least some new races, and maybe skills, though to do it.
